In the story, she could be making a statement about modern relationships. She wants to be completely open and honest with her husband about her body and her choices. By not wearing panties, she is showing that she trusts him completely and that there are no secrets between them when it comes to her physical self.
It's a rather personal choice. Some might argue it's inappropriate in public settings as it goes against social norms of modesty. But in a private, comfortable home environment, it could be about personal comfort or a form of sexual liberation within the relationship. However, in public, it can make others uncomfortable and may violate certain decency laws in some places.
It's not a simple matter of being appropriate or not. In different cultures, the perception varies. In some Western cultures that are more liberal, it might be seen as a bit of a risque but not completely unacceptable behavior in certain private situations. But in more conservative cultures, it would be considered highly inappropriate. As for reasons, it could be related to body comfort. Maybe she finds traditional undergarments restrictive and just wants to feel free.
Maybe it could be some sort of power play in a really dysfunctional relationship. The wife might be trying to assert excessive control over her husband.
In some fictional tales, the wife might not wear panties as a result of a magical or supernatural influence. For example, if there is a spell or curse that makes her feel uncomfortable wearing them. Another aspect could be that she is trying to make a statement about body acceptance and comfort. By not wearing panties, she is showing that she is at ease with her body and doesn't need to follow the typical undergarment - wearing rules. Also, in a story about a character's journey of self - discovery, this could be a small part of her new - found boldness and independence.
One reason could be a medical condition. For example, if someone has a skin allergy to the fabric of panties, it would make wearing them uncomfortable or even painful. So in the story, the character might be dealing with this itchy rash every time they try to wear panties and thus can't do it.
One reason could be for comical purposes. The wife might think it's really funny to see her husband in panties and wants to create a light - hearted moment in their relationship.
One reason could be a weak bladder. This can be caused by factors such as pregnancy or aging, which can lead to involuntary leakage.
One possible reason could be discomfort. Maybe the panties are made of itchy fabric or are too tight. Another reason might be a sense of rebellion against what she perceives as a strict rule. For example, if she feels that her parents are always forcing her to do things a certain way, not wearing panties could be her small form of resistance.
One reason could be for fashion. The wife might have a better sense of style and wants her husband to look good even in his undergarments.
It could potentially be part of some very dark and inappropriate power - play in certain extreme and unethical fictional stories. However, this is not acceptable behavior in real life.
